Question about Dell Latitude C840 Notebook
I upgraded RAM from 512 MB to 1024 MB ram but my notebood not accepting it.. on each start it asked for F1 command on starting
There are a lot of reasons your laptop is not accepting the new memmories
1) If it is an old laptop the motherboard might not support upto 1 GB of memmory
2) It can also be due to the fact that the connections are loose and the ram is not properly inserted or dust is interfering the contact
3)It can also be due to the difference in frequency and latency of the new ram you inserted
4)it can also happen when the frequency of the ram exceeds the frequency supported by the Front Side Bus(FSB)re it is compatible and also ensure that it is properly fixed
Check the ram ratings and make su

It is OK to mix chip (SODIMM) capacities in the 2 slots in your notebook.
The best system performance will be when you have 2 x 512MB but for now if you install 1 x 512MB, you could even leave the old chip in the other slot, it'll be fine.
